I currently have a JR 9303 and have been shot down twice by someone turning on there equipment in the past 3 years. So I'm considering selling my 93093 for the DX7. So I was wondering how they would stack up against each other. Currently I fly 2 trex's (one day and one night) and a evo 50. The evo has a gov. and HH gyro so it would seem that I would take up all the slots for the RX on the DX7. I just like the idea of no lockouts thanks to some idot. Or the ocasional glitch that I may get on the trex. But I dont want to loose quality in response time that I get with my 9303.

Just trying to get some ideas thanks for any advise.

Thanks, T.J.

I saw a video of Danny Szabo flying a trex 600 somewhere with a soon to be released spectrum module fitted in the 9303, could be worth waiting for........

NO WAY keep your 9303 and let them work all the bugs out and let them come down on price and come up on the number of channels . They will have a 8 9 and 10 or more channel spectrum sooner than latter to many people need a large number of channels so they are probably in the works now making one up . I would wait let the competition direct the price and then get yourself one .

If you are looking to avoid shootdowns, your 9103 isn't going to help you in that department.

If you are looking for speed, look at the DX7/AR7000 versus the 9103/649S in this thread. The DX7 wins.

That said, I understand your concern over goign from a high quality, 9 channel RX to an entry level 7 channel TX, but I decided to just get a DX7 now and swap it for a 9+ channel model when they become available. I want the safety and performance advantages now. In our hobby, technology updates are just a fact of life.

It's a pretty personal decision in the end. There are no wrong answers as both are good choices for their own reasons.

I agree with martinic but don't you think it won't be to long till they come out with a 9 or 10 channel model . Then you have to if needed buy another RX . So waiting isn't a bad idea . The product is great nothing can be said about that but waiting would be a wise thing to do ! Wouldn't you agree ?

I hope you're right Scott, but the DX6 was released a year ago in Dec., we now have the DX7 in Dec. (with signifcant improvements mind you - DSM2, model match, etc.) and so I expect it will be Dec. 2007 before we see a DX9. DX12 in Dec. 2008?

I suspect we'll see other alternatives from other manufacturers in 2007 - maybe that will cause Horizon to go to a more agressive release schedule.

If NIM's reason for looking at the DX7 is to avoid another shootdown, then waiting could cost him another crash or two...

So does that mean we can fly just like them?

I downloaded the DX7 manual and have placed one on order. By reading through the manual, it has everything that I need in a heli radio. I have the DX6 in my T Rex and I use the Futaba 8UHPS in my EVO 50. Chuck

Which gov. are you running?
The nice thing about the 9303 is it has a gov. program and that means you don't have to use any program mixes to use a TJ pro. The DX7 will require the use of program mixes when using a TJ or similar gov.
The DX7 will be a nice radio, but in my opinion it will lack some of the features that I have come accustom to using the 9303.
I am sure there is a DX9 in the works and will more than likely use the 9303 as its platform. I think spread spectrum is the future and as soon as the DX9 becomes available I will get one.

If you need 2.4ghz now, (or very soon) buy a DX-7 but keep your 9303. The XPS 2.4ghz system should be available early next year and possibly by Christmas this year (not holding my breath). That system is 8 channels minimum and they have a 12 channel and 16 channel coming soon. The options to add full telemetry will be available also. You will just plug the module into the back of your 9303 and put the receiver in your model. Any size model, as far as you can see it. I am getting both as they come out as I already have a DX-6 system (JR6102DX with extended runtime mod) and a JR XP8103A. I can't get what I want for the 8103 so I am keeping it and will use the XPS system in it. Since the smallest receiver is 8 channel, it will match nicely. After flying both for awhile I may choose to sell one or the other. Either one should sell rather quickly since they will both be on 2.4ghz.

I guess what I am saying they have two out and functioning so they have most the bugs out so it's nothing now to add a few more channels to the box . Now that may be the most stupidest thing I may have ever said Because I am not a designer of this technology but I am not a dumb man by no means . I don't think it will take that long before a 8 or 9 is out . That's my prediction for 2007 . Hope I am right . I have a 9303 and I am waiting .

My concern with the XPS system is latency issues which I believe there are going to be.
If the module option was a viable option then I think Spectrum radio would have gone that route, but for some reason Spectrum didn't go the module route for upgrading existing 8103 and 9303 radios.

I don't know how there are going to do it but like I said in my last post was if they went from 6 to now 7 channels I wouldn't think adding 1 or2 more channels would be that more difficult . So I just think a 8 or 9 channel will be out sooner than latter . Now they may wait and let us droll for a while but there is to many many rigs out here that have to use a 9 channel radio . So I can't see JR waiting to add the 2 channels They probably have one on the bench now working on it as we speak . At least I would like to think so . We will know soon enough .

According to Jason Krause, the XPS system latency comes very close to a 14MZ in 2048 mode. So the DX7 would still have an edge over it.
Neither the DX7 or the XPS are in the hands of a lot of 'normal' flyers so any bugs are still to be discovered.

In may 06 at the ST louis funfly I talked to one of the head designers/rep for Spektrum that was at our field he had about 8 trex's and 2 nitros. A bunch of us asked why they didn't want to produce modules for other systems. He basically stated that they wanted to produce there own line of radios (more money in it). This guy new more about 2.4 ghz than I can ever imagine.

Horizon hobbies: I called them this weekend and was talking to one of there technician's and was asking if the would be coming out with a higher end radio something like a DX9. He said officially he cant say yes, But then he told me that he knows they have it in the works.

As far as the XPS system the smallest RX is an 8channel and I don't think it will fit in my Trex. However this would work great in my EVO 50 but I would rather only have one radio for simplicity.

I think for now I will wait for them to produce the next higher up model from the DX7. I just hate the fact the my heli has gone down twice due to someone Else's negligence. There stupidity cost me over $600 dollars.

Thanks, T.J.

Nope...
NIM,
Ignore all these fine answers and just go ahead and sell me your 9303 for a really good (lets say "cheap" ) price and we can go forward with our flying and not be bothered by all this nonsense.

Just kidding!!! The advise about keeping what you have and going with the DX 7 now is great advise. That way you'll have something to fall back on if things get out of hand with the DX7. Remember this is "Version 1" of the DX 7 and there are always Service Pack 1's 2's...etc coming down the road. Can you tell I work in the IT/Computer field?

Later...

Scott!

Well, I just sold my 8103 and I have my DX6 up for sale as well. With the sale of the 8103, the last of my 72 MHz kit is gone (Including a 649S, a couple of Berg IIIs and an R700). This is being replaced with a DX7/AR7000 and some AR6000s (which I've been flying all year long with tremendous success).

When the DX9 or DX12 comes out late next year (after next flying season, I suspect), I'll just ell the DX7 and upgrade. Transmitters sell very well.

No more asking others on my channel if there transmitters are on, no chance of shootdowns. That means safer flying, and more flying opportunities for me.

Each to his own I suppose.

Martinic you are thinking kinda on the same lines as I . They will have a DX9 it's just when . The demand is out there so the old saying supply the demand . Then you will go far because if JR doesn't someone else is already in the labs waiting for them to drop the ball and then I guarantee you will see bigger channel radios and probably a little less expensive for the first little while . This is just my opinion so Lets wait and see .
